keessforshee: any chance you can take the patch for LP: #1766052 ?15:41
ubot5`Launchpad bug 1766052 in linux (Ubuntu Bionic) "Incorrect blacklist of bcm2835_wdt" [Medium,Triaged] https://launchpad.net/bugs/176605215:41
sforsheekees: we'll have to get acks, but the patche looks like it's missing a pipe15:47
* kees covers his face15:48
keesI'll send a v2.15:48
sforsheethanks, I'll ack it when it comes15:49
sforsheereplying to the original15:49
keesv2 sent15:51
kamalkees, sforshee: it feels icky to me, stuffing that raspi-specific exception into the generic 2-binary-arch.mk (and that it presupposes that no other platform would build bcm2835_wdt anyway (?))16:29

sforsheekamal: the driver depends on ARCH_BCM2835 so we're only talking about arm6417:02
sforsheeand we don't really have a way to say "don't blacklist only if installing on raspi"17:02
sforsheeat least none that I know of17:03
kamalsforshee, yeah, I don't see any already-existing better solution either, but IMHO, that "don't blacklist this specific driver" should be encoded in raspi2's abi somehow -- not just hardcoded in 2-binary-arch.mk17:08
kamal*in raspi2's abi dir somehow17:09
sforsheekamal: this is the generic arm64 kernel not the raspi2 derivative17:09

keeskamal: One idea I had was to not blacklist watchdogs with hardware aliases, since they're _supposed_ to be autoloaded.17:21
keesbut then, what's the point of the blacklist? I don't understand why that exists anyway...17:22
kamalkees, it was apparently implemented to fix some other broken hardware: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/143283717:25
ubot5`Ubuntu bug 1417580 in linux (Ubuntu) "duplicate for #1432837 HP Proliant Servers Advices for Ubuntu Linux (cmdline, panics, firmware options)" [Undecided,Invalid]17:25
keeskamal: hmmm, well, I think the global blacklist is a bit too wide. :)17:34
kamalkees, I agree!17:36
keesalso, it looks like systemd's systemd-load-module regressed from the /etc/init.d/kmod handling of explicitly loaded modules17:37
keesi.e. I used to be able to put modules in /etc/modules and they would get loaded.17:37
keesunder 18.04, they're checked against the blacklist.17:37

maccam94I want to test a bugfix for perf, is there a handy command to rebuild just the linux-tools-<version>-generic package? (preferably with pbuilder/debuild) i have the source checked out already21:51
